It looks well laid out the only option that looks like it couldn't exist without another is if some wisenheimer wants a secondary tone without ordering a primary. You may want to have an option that leaves the location of unspecified functions up to you to achieve a quieter wiring job. Ex I want the A function to be gain so I can hot foot it with my toes and I want no toggles next to A but everything else is up to you.
You need a price for the Hermaphrodite which is ALL the pots and switches (15) in a 7"x4.5" box.
You could offer color choices on the knobs obviously this could be an ordering nightmare but I feel if you make people aware that you (the builder) have to pay more for 4 of something instead of the discount of buying several hundred people will understand. I feel that it would add to overall custom theme at minimal hassle but maximum fun.
From a website perspective, it'd be way better to display the features as an image or a separate page on the site rather than a Docx file. A lot of people still haven't moved to the newest word (or use a program like open office) and can't read docx files. Plus, one click is easier than download and open.
